The ionosphere of Venus from the data of the satellites "Venera-9, 10" and some singularities of its formation

Abstract

We present novel real-space renormalization results for a lattice model of the collapse (coil-globule) transition of a polymer molecule adsorbing to a wall. These results support the conjecture that adsorption stabilises the collapsed phase by enhancing the collapse transition temperature. The analysis is developed, in both two and three space dimensions, for a suitably modified version of a recently proposed geometrical self-attracting self-avoiding walk model of polymer collapse.
